Disabling color profile handling

Some JPEG images have a color profile embedded such as sRGB or AdobeRGB. Opera 32 and Chrome tries to convert this to my monitor's profile, but they fail miserably at doing this properly, leading to ugly banding which is especially visible on clear sky photos and such. I'd rather not have Opera trying to do anything to the colors than this.

There seems to be a parameter called --enable-monitor-profile which you can specify on the command line, but it seem this is already enabled by default. Is there a way to disable this?
